However, the disadvantage of this technical solution is that it cannot automatically increase or decrease the counterweight weight of the support. Summary of the Invention

[0003] The purpose of this utility model is to provide a counterweight compartment to solve the technical problem of not being able to automatically increase and decrease the counterweight weight of the support.

[0004] To achieve the above objectives, the specific technical solution of the counterweight compartment of this utility model is as follows:

[0005] A counterweight compartment includes a mounting frame, a drive cylinder, a bracket, a support column, a compartment frame, a compartment extension frame, a compartment block, a first engaging lever, a first engaging lever push spring, a second engaging lever, a second engaging lever push spring, a slot, a third engaging lever, a third engaging lever push spring, an electromagnet, a fourth engaging lever, and a fourth engaging lever push spring. The mounting frame is equipped with a drive cylinder, the output shaft of which is mounted on the bracket. The bracket is slidably connected to the mounting frame. A support column is fixedly mounted on the bracket. The compartment frame is fixedly mounted on the mounting frame. A fourth engaging lever is slidably mounted on the compartment frame. A fourth engaging lever push spring is provided between the fourth engaging lever and the compartment frame. The fourth engaging lever is connected to the compartment block. An electromagnet is mounted on the support column. A second engaging lever push spring is installed between the electromagnet and the second engaging lever. The second engaging lever is slidably connected to the support column.

[0006] Furthermore, the second locking lever is made of magnetic material and can be attracted by an energized electromagnet.

[0007] Furthermore, the configuration block has a slot A that is compatible with the four-way locking lever.

[0008] Furthermore, multiple configuration blocks are configured.

[0009] Furthermore, the support column extends through multiple configuration blocks.

[0010] Furthermore, multiple mating levers are provided, and the multiple mating levers are arranged in a linear array along the configuration compartment frame.

[0011] Furthermore, a configuration compartment extension frame is slidably mounted on the configuration compartment frame. The configuration compartment frame has a mating slot, and multiple mating slots are provided. A mating rod three is slidably mounted on the configuration compartment extension frame. A mating rod push spring three is provided between the mating rod three and the configuration compartment extension frame. The mating rod three is mated and connected with the mating slot.

[0012] Furthermore, a first mating lever is slidably mounted on the configuration compartment expansion frame, and a first mating lever push spring is provided between the first mating lever and the configuration compartment expansion frame. The first mating lever is adapted to the slot A on the configuration block.

[0013] Furthermore, the plurality of the mating slots are arranged in a linear array along the configuration compartment frame.

[0014] Furthermore, the spacing between two adjacent configuration blocks is equal to the spacing between two adjacent mating slots.

[0015] Furthermore, the bracket has a trapezoidal groove A, and the mounting frame has a trapezoidal protrusion A, with the trapezoidal groove A and the trapezoidal protrusion A slidingly limiting each other.

[0016] The advantages of this utility model are:

[0017] 1. Start the drive cylinder. The drive cylinder, through the extension and retraction of the output shaft, drives the bracket to move up and down along the mounting frame, and also drives the support column to move up and down. When the support column moves downward, it contacts the configuration block through the engagement rod two, causing the engagement rod two to slide inward and retract into the support column. When the support column drives the engagement rod two to the lower end boundary of the configuration block, under the action of the spring engagement rod push spring two, the engagement rod two pops out and contacts the lower end surface of the configuration block. As the bracket and support column move upward, the configuration block is loaded, increasing the counterweight of the bracket. At the same time, the electromagnet is energized, causing the electromagnet to generate magnetic force, which overcomes the elastic force of the engagement rod push spring two, attracting the engagement rod two, causing the engagement rod two to retract into the support column. The loaded configuration block slides down to the lower side of the engagement rod two under the action of gravity, reducing the counterweight of the bracket. Thus, the counterweight of the bracket is automatically increased and decreased.

[0018] 2. The relative sliding configuration compartment frame and configuration compartment extension frame increase the total number of configuration blocks that the configuration compartment frame can accommodate. Attached Figure Description

[0033] Example 1

[0034] like Figure 1-11As shown, a counterweight compartment includes a mounting frame 1, a drive cylinder 2, a bracket 3, a support column 4, a compartment frame 5, a compartment extension frame 6, a compartment block 7, a first locking rod 8, a first locking rod spring 9, a second locking rod 10, a second locking rod spring 11, a locking slot 12, a third locking rod 13, a third locking rod spring 14, an electromagnet 15, a fourth locking rod 16, and a fourth locking rod spring 17. The drive cylinder 2 is mounted on the mounting frame 1, and the output shaft of the drive cylinder 2 is mounted on the bracket 3. The bracket 3 is connected to the mounting frame. The frame 1 is slidably connected. A support column 4 is fixedly installed on the bracket 3. A configuration compartment frame 5 is fixedly installed on the mounting frame 1. A matching lever 16 is slidably installed on the configuration compartment frame 5. A matching lever push spring 17 is provided between the matching lever 16 and the configuration compartment frame 5. The matching lever 16 is connected to the configuration block 7. An electromagnet 15 is installed on the support column 4. A matching lever push spring 11 is installed between the electromagnet 15 and the matching lever 10. The matching lever 10 is slidably connected to the support column 4. With this configuration, the drive cylinder is activated. 2. The drive cylinder 2, through the extension and retraction of the output shaft, drives the bracket 3 to move up and down along the mounting frame 1, and also drives the support column 4 to move up and down. When the support column 4 moves downward, the second locking rod 10 contacts the configuration block 7, causing the second locking rod 10 to slide inward and retract into the support column 4. When the support column 4 drives the second locking rod 10 to move to the lower end boundary of the configuration block 7, under the action of the spring-loaded locking rod push spring 11, the second locking rod 10 pops out and contacts the lower end of the configuration block 7. The surface contacts the support, and as the bracket 3 and support column 4 move upward, the configuration block 7 is loaded, increasing the weight of the bracket 3. At the same time, the electromagnet 15 is energized, causing it to generate magnetic force, which overcomes the elastic force of the second spring 11 of the locking lever and attracts the second locking lever 10, causing it to retract into the support column 4. The loaded configuration block 7 then slides down to the lower side of the second locking lever 10 under the influence of gravity, reducing the weight of the bracket 3. This allows for the automatic increase and decrease of the weight of the bracket 3.

[0035] Furthermore, the second locking lever 10 is made of magnetic material and can be attracted by an energized electromagnet 15.

[0036] Furthermore, the configuration block 7 has a slot A that is adapted to the mating lever 16.

[0037] Furthermore, the configuration block 7 is configured in multiple ways.

[0038] Furthermore, the support column 4 passes through multiple configuration blocks 7.

[0039] Furthermore, multiple mating levers 16 are provided, and the multiple mating levers 16 are arranged in a linear array along the configuration compartment frame 5.

[0041] like Figure 1-11 As shown, a configuration compartment extension frame 6 is slidably mounted on the configuration compartment frame 5. The configuration compartment frame 5 has a mating slot 12, and multiple mating slots 12 are provided. A mating lever 3 13 is slidably mounted on the configuration compartment extension frame 6. A mating lever push spring 3 14 is provided between the mating lever 3 13 and the configuration compartment extension frame 6. The mating lever 3 13 is connected to the mating slot 12. With this arrangement, the total number of configuration blocks 7 that the configuration compartment frame 5 can accommodate is increased relative to the sliding configuration compartment frame 5 and the configuration compartment extension frame 6.

[0042] Furthermore, a mating lever 8 is slidably mounted on the configuration compartment expansion frame 6, and a mating lever push spring 9 is provided between the mating lever 8 and the configuration compartment expansion frame 6. The mating lever 8 is adapted to the slot A on the configuration block 7.

[0043] Furthermore, the plurality of the mating slots 12 are arranged in a linear array along the configuration compartment frame 5.

[0044] Furthermore, the spacing between two adjacent configuration blocks 7 is equal to the spacing between two adjacent mating slots 12.

[0045] Furthermore, the bracket 3 has a trapezoidal groove A, and the mounting frame 1 has a trapezoidal protrusion A, with the trapezoidal groove A and the trapezoidal protrusion A slidingly limiting each other.
